1956年我队因岩心採取率过低而造成鑽孔报廢价值达数万元,这是很严重的。究其原因,主要是在工作中对岩石性質,地層構造掌握不够;和技术管理落后、操作不統一所致。經努力,从实际工作中,我們对所勘探地区的岩石,岩層的特点和其構造規律,有了进一步的了解,並掌握了这些特点和規律,从而使岩心採取率由30％提高到70％以上,基本上滿足了地質的要求。茲就个人的一点体会提出与大家研究。
In 1956, the rate of drilling scrapped by our team due to the low core rate was tens of thousands of yuan. This is very serious. The reason is mainly due to the lack of mastery of rock properties and stratigraphic structure in the work; and the backward management of technology and the inconsistent operation. After hard work, we have got a better understanding of the features and laws of the rock and rock formation in the areas we explored, and mastered these characteristics and laws so that the core adoption rate will be raised from 30% to 70% Above, basically meet the geological requirements. It is my personal experience and proposed to study with everyone.
